Mu Chen transmigrated into a primordial chaos spiritual body, bound to the fishing system, upholding the survival philosophy of not going out until invincible, and secluded himself to fish at the innate water pool in the southern cloud sea. Relying on the system's choices to reap opportunities, he casually enlightened Hongjun and Nvwa to help them attain enlightenment, rejecting the Primordial Purple Qi and the Purple Heaven Palace's sage position. Mu Chen saved Ancestor Hongyun to obtain his origin and the innate gourd, subdued the dragon clan's Aotian and the qilin Qiyan, and was gifted three infant phoenixes by Nvwa after she became a sage. He safely weathered the Longhan, Lich, and other primordial catastrophes, his strength steadily skyrocketing, ultimately becoming a top powerhouse hiding deep within the primordial world.
